This invention relates to improvements in the spinning rings of spinningmachines on which the thread guides or travelers; are

One of its Objects is the provisioniof a self-lubricating ring of this character which is so designed as to prevent the lubricant deposited on the bearing face of the ring being thrown or sprayed outwardly onto adjoining bobbins and soiling the threads. 1

Anot-her object of the inventionis to provide a spinning ring having means for efbricant over its bearing surfaces. j

Similar characters of reference indicate corresponding parts throughout the several Referring now to Figure showing a part of a'spinning machine of ordinary construc- *tion,'10 indicates the take-up spool applied to the revolving spindle -11 driven by the -belt 12 engaging the spool-pulley 13. In

machines ofthis characte r,there is af set of feed rolls for the threads to be twisted and 1 a take up spool for each vertical row of supply bobbins and traversing the several takeup spools from end to end' thereof is a vertically-reciprocating bar 14, each spool extending througha corresponding opening 15 in the bar. 'Mounted on the top of the lat- :ter and surrounding the companion take-up spool 10 is a traverse ring16 upon which the bar traveler 17 is adapted to revolve. During the operation of the machine, the bar traveler assumes a substantially uprightposition and revolves-with and about the takeeler-be'forebeing woundupon the spool, and

spool in layers.

v As: shown-in Figures 2 and 3; the traverse on yieldable brackets 18 rising from a basering 19' suitably fastened to the reciprocat- 'ing bar '14. The'inner" edge of the baseringterminates' in an upwardly-facing annular flange 20 which is spaced {from the ln'ner edge of the traverse ring toproduce an annular channel 121 for receiving the" depending legs of thebar traveler. The lower side of the traverse ring is spaced from the top of the base-ring 19 to producea lateral continuation of the bar" traveler receiving channel and 'suchfside'is slightly flared or beveled upwardly and outwardly, providing a bearing face for the bar traveler.

The

inner edgeof'the top wall of the cover se'c tion 26 is preferably turned downwardly to form a, flange 27' which produces a smooth, finished surface. The inner wall 28 of the grooved ring-section 24 isrpr'eferably conveXlycurved at its'inneredgeand slightly overlaps the Lflang'e ofthe" cover section in spaced relation to produ'ce" 'the*"res'tricted passage 23' for the emission' or delivery of a fpositioned adjacent to-thedepending guard v the lubricant directly on to the curved lface of said wall 28 and belowthe top wall of the cover section, as seen clearly in'Figures 3 and 5. It will be observed in these figures that the topisurface of the cover section 26 is slightly inclined downwardly and inwardly and that the lubricant passage 280f thering is below the level'of the outer top side of the lubricant chamber 22, resulting in'a gravity feed of the lubricant from said f-"chamber through its restricted passage. -However, the head pressure on thelubricant is not suf- 'ficient' to force it freely through thepassage 23, due to the adhesion of the lubricant to the passage-walls, and the lubricant forms' in a" thinfilm or. fillet at the meeting-edges of the ring parts 27 28. -Asfthe traveler revolves about the traverse ring, it picks'up sufficient oil to constantlyv and thoroughly lubricate the lower bearing surface of the ring, the oil 7 flowing down the legs of the traveler and thence outwardly by}centrifugal force where it deposits a film of oil on said bearing surface. c v; I

In its topside the cover section 26 of the traverse ring has one or more vents 30 which serve not only toeliminate the formation of undersurfiace or hearing side of the traverse ring-wl 1ere1it is required to effectually lubricate, the bar traveler, and to eliminate thev spraying'iof anysurplus oil or lubricant onto adjoining bobbins,'I,provide a guard rim or .retaini-ng member-at the periphery of the ring. .As. clearly shown. in Figures 3 and 5,

this guard rimis in the form, of'a depending l annulajr flange 32 which may be formed; in- :tegrally with the cover-section26 of the ring,

being'a continuation of its outer-wall, and extends .some'what below thei'lower bearing side "of the base section'24 oftheringthe lower edge of the. flange .terminating above the ring-holder 19' and resting on the brackets 18 jthereof; iBy'this construction, any surplus on delivered to the underside of thering is directed againsttheguardflange 32 and col- "lects in' theiform of a'fillet in the corner described by the adjoining faces ofthe ring and sa d guard flange. ;:The consistency of the foil and 7 its; capillary attraction retains it in thismanner and the lubricant has a'itendency to flow downwardlyand inwardly in a thin .film 'onthe lower'inclined bearing side of the 1 ring so as to efl'ectuallyv lubricate it.

Inits undersidejor bottom wall the traverse: ring has comparativelyismall lubricant discharge :port' 83 which 'is' preferably Figure 5. The lubricant discharged through this port assumes a small semi-globular form about the lower endof the port, the consistency. of the oil and its capillary attraction producing this result. As the bar traveler WVl-iile the sections 24, eemay be joined in any approved manner to form the hollow traversering, I prefer to hold these parts flange 32, where itis beyond the normal path 7 of travel of the traveler bar legs, as seen in traverses the ring, its legs dip into the puddle formed about the port and infso doing pick upsoine of the lubricant to lubricate it;
